Never Seen This Before Need Help PLease

Ok so here is the run down
strain- Girl Scout Cookies
Soil- cocoloco
Nutrients- flora duo armor si florliscious plus cal/mag
water- r/o
ppm-850
ph-6.0.
temp 75-77
humidity-42-48

So first time feeding them using the duo series. I always flower with duo and veg with the GH 3 part. Fed once with the recommended dosage and this is what happened. After they weirded out i flushed with water ph was 6.3. Then for a light feeding i was giving Liquid Karma and cal/mag ph 6.2 ppm 450. Still look pissed at me. Im ready to switch to 12/12 but not when they hate me lol. Also the lights are 26 inches from the tops hps 1000 hortalux Any help please ill take it. Been doing this 2 years and never seen this before. Mahalo for the help

You learn something every day, plants aren't perfect , looks like it could be a bit warm in there.

I was thinking the same thing but the temps aren't getting any higher then 78 lights on lights off 68. I have three fans going over the girls. My first thought is its the new r/o system i implemented. First time i used r/o water might of been a over feed but you'd think they would have snapped out of it by now. lol

I think ph is too high for coco causing lock outs look into that I remember reading somewhere that coco ph needs to be lower than actual soil Ph.

Any coco pros out there chime in and help this fella please.

also I know any cookies strain is finicky

ya coco is more like hydro then it is soil, want closer to a 5.5-5.8 range and imho, aslong as your water isn't too warm 78 is fine as light on temps

When I called bushdoctor who makes cocoloco they said its more like half soil half coco so I kept my ph at 6.2. Should I drop my ph more? I lowered the lights to 500 to try and combat the cannoing. Other wise im just at a loss. Thank you for any and all help

i would just treat it as normal coco but thats just me, but i have no experience with coco only hydro with the use of DWC bubble buckets so i really can't say for sure... but based on everything i've been told about coco i would say treat it as a normal hydro

your plants look good btw, so you must be doing a bunch of things correct to get this far

Anywhere from 5.5 to 6.5 will work with coco.

Anything with peat in it should be treated as soil. Coco is pH neutral.
I'm thinking more lighting is to close or you don't have enough nute's built up to handle that intense of lighting.

so the cannoing is from the ph or from lights? And even though it's not full coco still lower the ph?

i think heat is a issue too,have you thought about do a soil test to see were you are on the PH ,if the soil is running a 7.0 already and you nute them from 550 to750 on ppm that would raise that PH even higher ,do a soil test see what your running and adjust acorddinly,just my opinion it's worth a shot right

The Bush Dr. website doesn't say what is exactly in cocoloco except for coir and forrest humis. If it has any peat in it pH at 6.5

I would have guessed those brown spots on your last pic was a calmag def, but you say you give her calmag. Are you getting at least 200ppm of calmag? If that is good, my next guess is bugs. Doesn't look like any bug damage I've had, but just check. RH is a little low, but shouldn't be a problem for plants that size. PH should be around 6.5. Let the soil dry out a little, but not bone dry. Your pots should feel light when its time to water. Do you have proper drainage?

what is the temp/humidity in the room? they remind me of a run a few winters ago when i was growing up in my pole barn in open air, and it got pretty cold at night (high 30's at times). colder temperatures and hotter temperatures will both make your leaves act wilty like that. sativa leaning GSC? It could also just be time to get a new soil strategy and start using different products.

I've kept the nighttime temps around 75 lights on 78. They seem to be doing a whole hell of a lot better. But still stressed looking. Im feeding now half strength and not as often. Top soil is bone dry while about 6 inches down is lightly damp. I'll let them go hungry before I feed again
